Foglamp

Foglamp provides an open-source observability layer for agent-based applications, seamlessly integrating with the Vercel Language Model SDK. Key capabilities include: • Comprehensive cost, latency, and token monitoring • Detailed distributed traces for every operation • Evaluation and quality checks for output • Customizable alerting for critical metrics • Track per-agent spend and performance This platform allows developers to gain deep insights into the runtime behavior of their applications. It offers a centralized view of performance, reliability, and expenditure across different models and agents. By instrumenting applications with just two lines of code, users can quickly start collecting vital operational data. Foglamp helps identify cost regressions, performance bottlenecks, and quality issues before they impact end-users. It facilitates real-time performance tracking, error detection, and prompt-response analysis for individual operations. The system supports scoring production traffic using code-based checks and model-judged evaluations, ensuring high standards for output. Ideal for engineering teams developing and deploying agent-based applications, Foglamp ensures clarity and control over operational metrics. It's an essential tool for maintaining application health, optimizing resource usage, and delivering reliable experiences.
